COMBINED nocxme AND REVOLVING cream.

Specification of Iietters Patent.

Patented Nov. 1, 1921.

Application filed May 17, 1920. Serial No. 382,100.

This invention relates to combined rocking and revolving chairs, andmore particularly to such chairs in which there is a universal rockingmotion.

The particular adaptation which has been selected for illustration is achair or device specifically adapted for use by small Olllldren, wherebythey may be placed in a safe place and amused while at the same timeaffording them opportunity for necessary exercising without attendantdangers.

The invention consists broadly in the provision of a rocking base with asurmounted chair or seat, which is capable of a revolving motion inrelation to the rocking platform. More specifically it consists of arocking platform surmounting a segment of a sphere whereby universalrocking movement of the platform may be obtained, and a chairor seatmounted upon an auxiliary platform, which is capable of horizontallyrevolving motion with respect to the rocking platform.

The object of the invention is the production of an amusement] chair andexerciser,

particularly for children of tender age.

Another object of the invention is the provision in such a chair ofadequate safeguards against injury to the user. Other and furtherobjects of the invention will hereinafter appear in the followingdescription, and the novel features thereof will be particularly pointedout in the appended claims.

In the drawings, Figure 1 is a plan view of the chair,

Fig. 2 is an elevation thereof, with certain of theparts shown insection, and

Figs. 3 and 4 are views of the coupling member, by which the rocking andrevolving platforms are connected.

The numeral 1 is used to designate the rocking platform, which is madeof wood, surmounting a bowl 2 in the form' of a segment of a, sphere,which bowl is of sheet material. The bowl is provided with a flange 3,which is attached to the under side of the rocking platform by screws 4.A

an increased diameter to provide a projecting portion around the bowl,so that in the rocking motion of the chair the periphery of the platformwill act as a stop or -limit, insuring safety in the use of the device.

Revolubly mounted upon the rocking platform is an auxiliary platform 6upon which is provided a seat 7 comprising a bottom 8, uprights 9 and abody support 10. The auxiliary or revolving platform is extended forwardfrom the open portion of the seat proper sufficiently to receive thelegs of the occupant, but otherwise conforms generally to the contour ofthe'seat proper. This seat is attached to the revolving platform byscrews or anyother suitable means.

The rocking and revolving platforms are connected together by a coupling11, which .is placed centrally of the rocking platform.

The revolving platform, however, is mounted eccentrically of the rockingplatform in order to secure equilibrium when the chair is occupied thatthe rocking motion of the devicemaybe produced with slight effort uponthe part of the occupant.

The" coupling may be of any approved form for permitting a rotarymovement between the parts, but the one chosen for illustrationcomprises a male member 12 and a female member 13. The male. member isprovided with a base '14 which isins'et in the bottom of the revolvingplatform, said base having projecting therefrom a stud 15 provided withan annular groove 17. The female member is mounted centrally upon therocking platform and is provided with an upstanding portion 18"having abore 19 into which the stud of the -male member takes. A screw 20 isscrewed into a threaded aperture inthe upstanding portion 18 and thereduced end thereof fits within the groove 17 of the male member whenthe parts are assembled, there being clearance lot sufficient betweenthe screw end and the groove to permit easy revolving motion.

Mounted upon the rocking platform is a hand rail 21 supported by bracemembers 22, which are so curved as to permit of ample space for themovement of the revolving platform and yet bring the hand rail 21 intoeasy access of the occupant of the device. The brace members are screwthreaded at one end to screw into the hand rail as shown at 23 and areprovided at the upper end with feet 24 by which they are attached byscrews to the rocking platform.

In the use of the chair the occupant is placed in the seat proper andstrapped therein if desirable with the legs projecting beyond the seatand supported upon the front portion of the revolving platform. Theoffset mounting of the revolving platform upon the rocking platforminsures when the device is occupied an upright position thereof. Aslight movement of the body of the occupant will cause the device torock upon the bowl member and another slight movement of the body of theoccupant will cause the completing of the rocking cycle. If the occupantdesires to face in any other direction, the hand rail, which isconveniently located, is grasped and the revolving platform caused toturn upon the rocking platform by a slight pull in the desireddirection. The curvature of the bowl is suchthat the rocking motionproduced is even and gentle.

It is obvious that a device has been devised, particularly for youngchildren, which will afford a means of exercising as well as amusement,and that the easy curvature ofthe bowl together with the projectingperiphery of the rocking platform and the provision of the hand rail andextended foot board contribute to making the device a safe one for theuse of children of tender years.

Having described the invention, what is claimed as new is:

1. An exercising chair comprising a universal rocking base, a chair orseat mounted upon said base and having independent rotary movementthereon, and a hand rail supported by the base and surrounding saidchair or seat.

2. In a combined rocking and revolving chair, the combination of auniversally rocking base comprising a spherical rocking surface and aplatform extended beyond the rocking surface to limit the rockingmovement, a revolving seat support mounted upon the said platform, aseat or chair supported thereon, said support being extended beyond theseat member to provide a support for the legs of the occupant, and ahand rail supported by the platform and accessible to the occupant ofthe seat.

3. In a combined rocking and revolving chair, the combination of arocking base comprising a section of a sphere, and a revolving chairmounted directed above said rocking base and eccentrically thereof.

4. In an amusement or exercising device, the combination of auniversally rocking base, a seat, means for mounting said seat upon saidbase to freely revolve thereon, and means supported on said base andwith relation towhich the seat is revoluble for permitting engagement bythe occupant of the seat to pivotally turn the seat upon the base.

5. In a combined rocking and revolving chair, the combination of auniversally rocking base, a revolving occupant support comprising bodyand leg sections and so mounted upon said base that when occupied theleg portion will substantially counterbalance the body portion.

6. In a combined rocking and revolving chair, the combination of auniversally rocking base comprising a spherical rocking surface and aplatform extended beyond the rocking surface to limit the rockingmovement, and a revolving occupant support comprising a seat portion andan extended leg portion and so mounted upon said platform that whenoccupied the leg portion will substantially counterbalance the bodyportlon.

In testimony whereof we aflix our signatures.
